1. The problem is to simplify the expression $(A + A')$ where $A'$ is the complement of $A$. 2. The formula used here is based on Boolean algebra rules, specifically the Complement Law which states that $A + A' = 1$. 3. This means that the OR operation between a variable and its complement always results in 1. 4. Therefore, the expression simplifies directly to 1 without any further steps. 5. In plain language, this means that either $A$ is true or $A$ is false, so the expression is always true. Final answer: $$A + A' = 1$$
